After installing postfix-2.2.10-1.RHEL4.2:2.i386 from U4 smtpd with tls support
stopped working. The update re-bases postfix from 2.1.5 to 2.2.10.
The maillog contained:
Aug 18 01:50:46 talyn postfix/tlsmgr[9152]: fatal: unsupported dictionary type: sdbm
Aug 18 01:50:47 talyn postfix/master[3570]: warning: process
/usr/libexec/postfix/tlsmgr pid 9152 exit status 1
Aug 18 01:50:47 talyn postfix/master[3570]: warning:
/usr/libexec/postfix/tlsmgr: bad command startup -- throttling
It seems that the format of the session cache changed. Previous to the update
sdbm was supported (as the only format according to the comments in the default
config file). In the new package version sdbm is not supported anymore. btree
works instead.
This change has the potential to disrupt customer production as the previously
working configuration suddently fails to work.
It is related to bug #202357 but in difference to it seems to be not fixed by
postfix upgrade-configuration.
